By far the single largest use of lead is in lead storage batteries. The group 14 elements all have ns 2 np 2 valence electron configurations. All form compounds in which they formally lose either the two np and the two ns valence electrons or just the two np valence electrons, giving a +4 or +2 oxidation state, respectively.

are used as semiconductors and insulators. Nonmetals. 2021-04-13 Group 4A is often referred to as the Carbon Group and contains carbon (a non-metal), silicon and germanium (metaloids), and tin and lead (metals). Each of these elements contains 4 electrons in The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table.

The Group 4A elements have four valence electrons in their highest-energy orbitals (ns2np2).

Usually, the semimetals or metalloids are listed as boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. Some scientists also consider tennessine and oganesson to be metalloids. The elements commonly classified as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. [n 4] The status of polonium and astatine is not settled.

On the Silicon and germanium, both metalloids, each can form +4 ions. Tin and lead both are metals, while flerovium is a synthetic, radioactive (its half life is very short , 17 Jul 2019 Semimetals or metalloids are chemical elements that have properties more recently, the preferred term for the element group is "metalloids," Elements can be classified as metals, metalloids, and nonmetals, or as a main- group elements, transition metals, and inner transition metals.

100 Further quantum chemical calculations showed that the stabilizing Elements in group 14 can be classified as non metals, metalloid and metals. Group 14 has C, Si, Ge, Sn and Pb as its elements. C is a non metal. Si and Ge are metalloids while Sn and Pb are metals.

It forms stable penta- and trivalent compounds, Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal.The term is normally applied to a group of between six and nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) found near the center of metalloid definition: 1. a chemical element with some of the properties of a metal and some of a non-metal, for example….
